Asian markets closed broadly lower on June 5, 2026, as selling pressure intensified across the region. The decline marked a second consecutive session of widespread losses, with South Korea suffering the steepest drop while weakness spread across Japan, Hong Kong, China, Australia, and India.

The session reflected growing caution among investors following May’s strong rally, as profit-taking and risk reduction dominated trading activity.

South Korea Suffers Sharp Correction

South Korea’s KOSPI Composite Index plunged 5.54% to 8,160.59, making it the weakest-performing major market in Asia during the session.

The sharp decline erased a significant portion of the market’s recent gains and reflects heavy selling in technology and semiconductor shares that had previously driven the KOSPI above 8,800. Despite the setback, the index remains well above levels seen earlier in the year.

The magnitude of the drop highlights the elevated volatility that continues to characterize Korea’s equity market.

Japan and Hong Kong Extend Regional Weakness

Japan’s Nikkei 225 fell 1.31% to 66,588.12, extending losses from the previous session and moving further away from its recent record highs above 68,000.

Hong Kong’s Hang Seng Index dropped 1.15% to 24,961.95, falling below the 25,000 level and continuing a pattern of underperformance relative to other major Asian markets.

The declines suggest investors remain cautious toward both export-driven and China-linked equities as broader risk appetite weakens.

China, Australia, and India Also Move Lower

China’s SSE Composite Index declined 0.74% to 4,027.74, extending its recent weakness and remaining one of the region’s lagging markets.

Australia’s S&P/ASX 200 fell 0.70% to 8,625.10 as commodity-linked sectors came under pressure.

India’s S&P BSE Sensex slipped 0.18% to 74,228.73, recording a relatively modest decline compared with other regional benchmarks but still reflecting the broader negative tone.

The fact that every major equity market finished lower underscores the widespread nature of the selloff.

Currency Markets Remain Relatively Stable

Despite the sharp decline in equities, currency markets remained relatively calm.

The Australian Dollar Index rose slightly by 0.07% to 71.39, while the Japanese Yen Index edged up 0.03% to 62.49.

The limited movement suggests investors have not yet shifted aggressively into defensive currency positions, despite heightened volatility in equity markets.

Outlook

Looking ahead, investors will closely monitor whether the sharp decline in South Korea develops into a broader regional correction or remains concentrated in previously high-flying technology sectors.

Key levels to watch include 8,000 for the KOSPI, 66,000 for the Nikkei 225, and 25,000 for Hong Kong’s Hang Seng Index. Market behavior around these levels could provide important clues regarding investor confidence and risk appetite.

For now, Asia’s markets have clearly entered a corrective phase, with profit-taking, elevated volatility, and cautious positioning replacing the strong bullish momentum that characterized much of May.
